IMPROVEMENT 1N' @ANd-snows.

s The Schedule referred to in these Letters Patent and making part t thev same.

To all whom it may concern Be it known that I, BYRON J ENNINGs, of Gilroy,

county of Santa Clara, State of California, haveinvented an Improved Gang-Plowf and vI do hereby in that class of gang-plows in whichthe plow-frame is-ma'de separate and att-ached't a truck; and

It consists in an improved manner o f operating thc' plowframe in' order to raise it and clear the plow from the ground.

It also consists in "an improved manner of attaching the frame to the truck, so that the operation of raising and lowering the frame is much simplified, and the amount of power required to be exerted is greatly reduced.

To more fullyillustrate and explain `my invention, reference is had to the accompanying drawings, forming a part of this specification, of which-- Figure l is a side-view.

Figure 2 is an enlarged view of the device for drawing the pin which holds the slide-bar.

Similar letters of reference, in each vof the figures,

indicate like parts." ,i Y i A is the frame, to which the plows are "attached, and

B, the truck.

In the usual form of constructing these plows, the

4two are connected by a link- 'wint, which, in oon-V nection with adjustable rods, enables the driver to hold the frame at variable heights,

parallel with the ground. l

In this plow, a shaft, C, extends along the axle, and parallel to it, turning -in 'clasps, a a., or other equivalent device, and has a lever, D, attached at one end. Extendingfrom this shaft are two short arms b l), the ends of which are connected with the plates d d oa the sides of the timbers' of the plow-frame.

The plates d d have two orniore holes e e in theirends, and a rod passes through one of the holesand a hole in the end of the arms b' l) on each side.

By attaching the arms l b in the upper or lower holes, the depth to which the plows out is regn- -1ated.

A curved armiy or lever, E, rises from the shaft O, to which the usual levers by which the plow-frame is elevated, are attaphed.

'Io the lower end of this lever is attached a curved bar, g, which passes down along 'the pole and'inside f of 'a guide, h, which is attached above and below the pole P. Y 'On the opposite side of the .pole is attachedga bent lever, F,which hasa vertical lug,'fi, depending' frointhe horizontal portion of tle curve.

This lug is provided with an inclined slot, as shown ing the inclined slot.

rIhe lever F extends upward, and is' bent at right angles at the top, so as to furnish a suitable bearingsurface for the foot of the driver in operatingit, and a spring, 1J, keeps it to its proper position. 4

I'Io raise the frame, the lever is depressed with the foot of the driver; this causes the lug t' to draw the pin n and release the sliding-bar g, when, .by throwing. the lever D toward the front, the shaft C is caused to turn, elevating the front end of the frame by lmeans of the arms b b, and. also raising the rear 'end by means of the series oi levers attached to the curved arm E.

When the lever F is released, the bent pin or staple is thrown back to its place by the inclined slot, thus xi-ngthe levers vin their position.

l This manner of' 'drawing a straight pin I claim as being Van entirely new device,'as' the pin is both drawn. and forced back to its place. by the lug, and it can be applied to various uses with ythe same result. l l V f By this construction, the depthv to which it is desired to plow is easily regulated, while -the ent-ire operation of elevating the plows out of the .groundis brought more directly under the entr-0l of the driver.

Having thus described my invention lWhat I claim, andpdesire to secure by Letters Patent, isf- 'l -1. lhe combination, with the arms l), on the 'shaft C, of the plates d, provided with holes e, for making 'their connection adjustable, substantially asv and for and seal.`
